The backdoor enable bit must be set in the SCM RAMBAR as well as
the secondary port valid bit in the Core RAMBAR in order to enable
backdoor accesses from the DMA to SRAM. See

Figure 14-4. Source Address Registers (SARn)
14-4, contains the address from which the DMA controller requests data.
DMA channel n. Each four bit field defines the logical connection between the DMA
requestors and that DMA channel.There are ten possible requesters (4 DMA Timers and
6 UARTs). Any request can be routed to any of the DMA channels. Effectively, the
DMAREQC provides a software-controlled routing matrix of the 10 DMA request signals to
the 4 channels of the DMA module. DMAC3 controls DMA channel 3, DMAC2 controls
DMA channel 2, etc.
